The door handling mechanism 28 and the door cleaning mechanism 27 are then rotated about shaft 55 and the movable support structure moved along so that the coke guide is opposite the oven chamber and the door handling mechanism together with the door is opposite the door cleaning mechanism 33. The coke guide is extended into its operative position, and the door handling mechanism is extended to bring the door into contact with the door cleaning mechanism (Fig. 2b). After discharge of the coke and cleaning of the door the coke guide and door handling mechanism are retracted, the movable support structure moves back to bring the oven cleaning mechanism opposite the door, whereupon the mechanism is extended towards the oven to effect cleaning of the sealing surface thereof. After retraction of the cleaning device the door handling mechanism 28 is rotated back into its original position to replace the cleaned door.

Abstract: 958, 970. Automatic voltage control systems. ATELIERS DES CHARMILLES S.A. Sept. 12, 1960 [Sept.12, 1959], No. 31354/60. Heading G2R. The supply system for an electrolytic cutter maintains constant the average voltage between the cutter and the workpiece, the time constants of the measuring circuit being chosen to reduce voltage surges. Direct current is supplied by transformer 1 and rectifier 10, 11 to the rotating cutter 12, and workpiece 13,which latter forms the anode. A portion of the cutter/workpiece voltage, tapped off coarse and fine potential dividers 19 and P, and a reference voltage obtained across a Zener diode 21 are applied to a transistor comparator T1, T2. Any unbalance controls a power transistor T3 which controls a saturable reactor L1 L2 in series with the supply to the transformer 1. The saturable reactor may be replaced by paralleled power transistors on the D.C. side of the supply. The cutter/workpiece voltage signal charges a capacitor C1 through parts of the potential divider resistors R7 when the signal is greater than the reference voltage. The time constant is made slightly less than the minimum period of uninterrupted cutting. The cutting is frequently interrupted by short circuits. The diode 20 prevents the capacitor C1 from discharging through R7 &c., during a short circuit and so it discharges through R11. The time constant of Cl,R11 is made longer than the maximum period of short circuit so that the system does not respond to changes in cutter/- workpiece voltage due to short circuits.

Abstract: 989,169. Oscillating machines. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 4, 1961 [Sept. 13, 1960], No. 31477/60. Addition to 899,678. Heading H2A. The reciprocating motor or generator described in the parent Specification is modified to provide a polenumber of more than two by shaping the D.C. excited poles so that they present more than one pole each to the short-circuited reciprocating coil 15. In the fourpole form shown in Fig. 1, the field members 20, 21 are excited by D.C. coils 22, 23 to produce opposite poles at their ends, the inner faces being backed off to produce an A.C. output in coils 19 of sinusoidal or other desired shape. As in the parent Specification, armature-reaction is reduced by a conducting pole-facing 24. If desired, the pole-members may be placed at the outer faces of the central core, and this serves to reduce the armature reaction further because the working flux passes into the faces of the core laminae and any flux variation would cause eddy-current in the laminae. If these arrangements are combined as shown in Fig. 3, a more powerful machine is produced. Effective six-pole operation is achieved by using two or more sets of field coils to produce a different polarity at the centre of the field members than at the ends, e.g. the ends may be of north polarity, while the central backed-off part is south. Higher pole-numbers may be achieved by using more coils to produce more poles on the field-members.

Abstract: 846,202. Synchronous motors. LANDIS & GYR A.G. Oct. 3, 1958 [Oct. 23, 1957: Sept. 8, 1958], No. 31689/58. Class 35. In a synchronous motor with permanently magnetized rotor the A.C. energized stator teeth 14, 20 of opposite polarity face one another (not interdigitated) while the rotor teeth 2, 3 of about half the width of the stator teeth, are bent out in opposite directions but are all polarized the same by two axially magnetized annular magnets 27, 18, one mounted on the rotor and the other fixed to the stator casing. The magnets are of a ferrite having a high coercivity but a reversible permeability of only about unity so that the polarity of the rotor teeth may easily be reversed by the stator flux without demagnetizing the magnets or providing a substantial shunt for the stator tooth flux. When the stator coil 25 is de-energized, the rotor takes up the position shown in Fig. 2 due to the polarization of the rotor teeth by magnets 18, 27. On energization of the coil the rotor teeth 2 or 3 will move towards the centre of the stator teeth depending on the phase of the first current wave. A reversing lock (not shown) is therefore provided. It is possible to provide two more magnets in mirror-image positions to 18 and 27 on the left-hand side of the rotor. The rotor may be made of an annular strip mounted on a rotor disc and stamped with alternate axial teeth. One of the permanent magnets may coincide in position with the axis of symmetry of the rotor, the magnets being radially polarized. In this case the rotor may comprise two discs having interdigitated teeth bent in the same direction or surmounted by a serrated strip. It is described (Figs. 5 and 6, not shown) how the rotor magnet 27 may be on the opposite side of the rotor disc from the fixed magnet 18 the magnets being axially magnetized in this case. The stator teeth may be bevelled to facilitate starting in one direction. Specification 846,203 is referred to.
